My favorite JRPG OSTs are Xenogears, Xenosaga I and III, Chrono Cross and Baten Kaitos 1.

X-2 had some great tracks, and one of the best ballads in video games with "1000 Words", but by and large it didn't wow me that much. I can only think of two memorable area themes for example. "Abyss of the Farplane" and "Bevelle's Secrets". And of the battle themes, I only like the last few for Vegnagun/Shuyin. I never liked the normal battle music or boss music.

But hey, let's mak ea new topic for that discussion. I made one a long time ago and it got no love at all so I'm glad to see X-2's OST does have some fans active on here now.
